Maxillary and mandibular molar and incisor vertical dimensions were evaluated in subjects who had excessive, normal, and short lower anterior face height in relation to upper face height. Sexual dimorphism was also investigated. The dentoalveolar heights were compared between Class I and Class II, dental and skeletal malocclusions. The sample was drawn from the Burlington Growth Centre sample and consisted of 188 male and 156 female subjects at age 12 years, for whom lateral head films were available. This sample was classified into excessive, normal, and short lower anterior face height, using the ratio upper anterior face height/lower anterior face height (UAFH/LAFH). The results showed that the dentoalveolar heights are significantly different between faces with excessive, normal, and short lower anterior face heights, except for the lower posterior dental height, which showed no difference between short and normal lower anterior face height subjects. All dentoalveolar heights are larger for male subjects except for the upper posterior dental height. Dentoalveolar heights are similar between Class I and Class II dental and skeletal malocclusions. The upper teeth present a higher correlation to the UAFH/LAFH ratio than the lower teeth. Stepwise regression analysis shows that 22% of the variation in the ratio is explained by the maxillary and mandibular molars and 41% is explained by the maxillary and mandibular incisors.
在那些相对于上面部高度而言，下面部高度过长、正常和过短的受试者中，对上颌和下颌磨牙及切牙的垂直尺寸进行了评估。还研究了性别差异。比较了安氏Ⅰ类和安氏Ⅱ类牙性和骨性错牙合之间的牙槽高度。样本取自伯灵顿生长中心样本，由188名12岁男性和156名12岁女性受试者组成，他们均有头颅侧位片。使用上前部面高/下前部面高（UAFH/LAFH）比值，将该样本分为下面部高度过长、正常和过短三组。结果显示，除了下后牙高度在下面部高度过短和正常的受试者之间无差异外，在下面部高度过长、正常和过短的面部之间，牙槽高度存在显著差异。除了上后牙高度外，男性受试者的所有牙槽高度均更大。安氏Ⅰ类和安氏Ⅱ类牙性和骨性错牙合之间的牙槽高度相似。上颌牙与UAFH/LAFH比值的相关性高于下颌牙。逐步回归分析显示，该比值22%的变异由上颌和下颌磨牙解释，41%由上颌和下颌切牙解释。
